Fingerprint research. Scientists working on a method of viewing fingerprints. Fingerprints are composed of amino acids,sebum,mineral salts and water. Here,the fingerprints are treated and fixed with indanedione and excited using a powerful green laser. The indanedione binds to the amino acids,which re-emit the laser's light by fluorescence. The fingerprints are therefore visible with the aid of special glasses or orange filters.
